Abstract

PROBLEM TO BE SOLVED: To provide a shift lever device capable of sufficiently taking a moving stroke of a shift lever and absorbing force without increasing the height when strong force is received. SOLUTION: A housing part 18 is formed on a lever holder 14 to which the lower end of a shift lever 12 is attached. A fixed shaft 20 and a retainer 22 are housed in the housing part 18, extending pieces 28 projecting from the opening edge of the housing part 18 are caulked, and the fixed shaft 20 and the retainer 22 are pinched. The shift lever 12 is offset from the fixed shaft 20 and the retainer 22, and the axis 26 of the shift lever 12 does not intersect the axis 24 of the fixed shaft 20. When the shift lever 12 receives impact force in the axial direction, the projecting pieces 28 are deformed, and the shift lever 12 and the lever holder 14 are downward moved.

[0004]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a shift lever device capable of absorbing the force by increasing the moving stroke of the shift lever when receiving a strong force without increasing the height. The task is to provide.

[0005]

According to the first aspect of the present invention, a shift lever capable of selecting an arbitrary shift range by a shift operation, a shift lever rotatable in the shift direction, and a shift lever A support member for supporting the shaft of the shift lever offset from the center of rotation of the shift lever, and the shift lever provided on the support member is capable of moving the shift lever in the axial direction by the impact force when the shift lever receives an impact force in the axial direction. And a shock-absorbing part for holding the shock-absorbing member.

Since the shift lever is supported by the support member so as to be rotatable in the shift direction, the shift lever can normally be rotated by a shift operation to select an arbitrary shift range.

[0007] Since the support member is provided with an impact absorbing portion, when the shift lever receives an impact force (strong force) in the axial direction, the shift lever moves in the axial direction by the impact force to absorb the impact force. can do.

Further, since the shaft of the shift lever is offset from the center of rotation of the shift lever, it is possible to obtain a sufficient movement stroke when the shift lever is moved in the axial direction by an impact force.

[0009] In the invention described in claim 2, the support member includes a shaft, and a lever holder to which the shift lever is attached in a state where the shift lever is mounted on the shaft and the shaft of the shift lever is offset from the shaft. Wherein the shock absorbing portion is a deformable portion formed on the lever holder and deformed when the shift lever receives an impact force in the axial direction to enable the shift lever to move in the axial direction of the shift lever. Features.

[0010] Since the lever holder to which the shift lever is attached is mounted on the shaft, normally when the shift lever is shifted, the shift lever rotates about the shaft integrally with the lever holder. Any shift range can be selected.

When the shift lever receives an impact force in the axial direction, the deformed portion is deformed, and the lever holder can move in the axial direction of the shift lever. For this reason, the shift lever moves in the axial direction of the shift lever integrally with the lever holder, and the impact force received by the shift lever is absorbed. Note that the deformation of the deformed portion includes plastic deformation, elastic deformation, breakage, and the like, and any deformation may be used as long as the shift lever can be moved in the axial direction.

Further, the shift lever is mounted on the lever holder with the shaft of the shift lever being offset from the shaft body. Therefore, the shaft does not hinder the movement of the shift lever in the axial direction, and the movement stroke of the shift lever can be made sufficiently long.

According to the third aspect of the present invention, the support member is provided with a shaft, a block mounted on the shaft, and the shift lever, and the support member is offset from the shaft and is rotated by the block. A lever holder that is supported so that the shock absorber can fix the lever holder to the block and deform when the shift lever receives an impact force in the axial direction to deform the shift lever in the axial direction. It is characterized in that it is a deformable portion that enables movement and rotation of the lever holder with respect to the block.

A lever holder to which a shift lever is attached is rotatably attached to a block attached to the shaft. Normally, since the lever holder is fixed to the block by the deformed portion, when the shift lever is shifted, the shift lever rotates around the shaft integrally with the lever holder and the block, and an arbitrary shift range can be set. You can choose.

When the shift lever receives an impact force in the axial direction, the deformed portion is deformed. For this reason, the lever holder can rotate with respect to the block. As a result, the block is pushed by the lever holder and pivots about the shaft body, and the shift lever and the lever holder move in the axial direction of the shift lever while being integrated, so that the impact force received by the shift lever is reduced. Absorbed. The deformation of the deformed part includes plastic deformation, elastic deformation, breakage, etc., and release of the fixing of the lever holder to the block enables the shift lever to move in the axial direction and rotate the lever holder with respect to the block. Any modification may be used as long as the modification can be made as follows.

Since the lever holder is mounted on the block offset from the shaft, the shaft of the shift lever mounted on the lever holder is also offset from the shaft. Therefore, the shaft does not hinder the movement of the shift lever in the axial direction, and the movement stroke of the shift lever can be made sufficiently long.

[0017]

1 to 3 show the main part of a shift lever device 10 according to a first embodiment of the present invention.

The shift lever device 10 has a shift lever 12 for a shift operation, and a knob 12A at the upper end.
The lower end of the shift lever 12 to which is attached is attached to a lever holder 14.

The lever holder 14 is formed in a substantially L-shape in a side view, and the lower end of the shift lever 12 is inserted and fixed in an insertion hole 16 formed in a long side portion 14A of the lever holder 14.

A housing 18 is formed on the short side 14B of the lever holder 14 and opens upward in FIG. 2. The housing 18 has a fixed shaft 20 and a fixed shaft 20.
The retainer 22 mounted in the housing is accommodated such that a substantially intermediate portion in the axial direction of the retainer 22 is held. The fixed shaft 20 is fixed over a pair of support plates (not shown) formed in the shift lever device 10. Also, retainer 2
2 is formed in a cylindrical shape, and is rotatably mounted on the fixed shaft 20.

In a state where the fixed shaft 20 and the retainer 22 are housed in the housing portion 18, the shift lever 12 is offset (length L) from the fixed shaft 20 and the retainer 22 and attached to the lever holder 14. For this reason, the axis 24 of the fixed shaft 20 does not intersect with the axis 26 of the lever holder 14.

A plate-like projecting piece 28 projecting in a direction approaching each other is formed at the opening edge of the housing portion 18, and a slit 30 is formed between the tips of the projecting pieces 28.
The projecting piece 28 is swaged in a state where the fixed shaft 20 and the retainer 22 are housed in the housing portion 18, and these fixed shafts 2
The retainer 22 and the retainer 22 are sandwiched between the bottom wall 18 </ b> A of the storage unit 18 and the retainer 22. Therefore, when the shift lever 12 is rotated in the direction of arrow A (see FIG. 2) by the shift operation, the retainer 22 is also rotated via the lever holder 14. A control lever (not shown) projects from the retainer 22, and a pin of the control lever is connected to the automatic transmission via a transmission mechanism. Therefore, the retainer 22 is rotated by the shift operation of the shift lever 12, so that a desired shift range can be selected.

Further, when the projecting piece 28 is pushed from the housing portion 18 side, it is plastically deformed so as to warp upward. Therefore, as shown in FIG. 4, when the shift lever 12 receives an impact force in the axial direction and the lever holder 14 is pushed downward, the retainer 22 relatively pushes the projecting piece 28 so as to enter the slit 30 relatively. , The overhanging piece 28 warps upward.

Next, the operation of the shift lever device 10 according to the first embodiment will be described. Normally, as shown in FIGS. 1 to 3, the overhanging piece 28 is swaged to hold the retainer 22 between the overhanging piece 28 and the bottom wall of the housing 18. Therefore, when the shift lever 12 is rotated in the direction of arrow A by the shift operation, the shift lever 12 is moved to the lever holder 14.
And the retainer 22 is rotated to select an arbitrary shift range.

When the shift lever 12 receives an impact force in the axial direction via the knob 12A during sudden deceleration of the vehicle, the lever holder 14 tends to move downward as shown in FIG. 28 is pushed upward relative to the retainer 22. For this reason, the projecting piece 28 is plastically deformed so as to warp upward, the shift lever 12 moves downward while being integrated with the lever holder 14, and the impact force received by the shift lever 12 is absorbed.

Here, the shift lever 12 is offset from the fixed shaft 20 and the retainer 22, and since the axis 24 of the shift lever 12 does not intersect with the axis 26 of the fixed shaft 20, the shift lever 12 moves downward. In this case, the shift lever 12 can be moved sufficiently without hitting the fixed shaft 20 and the retainer 22.

When the impact force received by the shift lever 12 is large, as shown in FIG. 5, the projecting piece 28 warps further upward to widen the width of the slit 30, and the fixed shaft 20 and the retainer 22 are accommodated. You may make it escape from the part 18. Thereby, a larger impact force can be absorbed. In this case, since the shift lever 12 and the lever holder 14 are completely separated from the retainer 22 and fall off, a cushioning material is provided below the shift lever 12 so that the dropped shift lever 12 and the lever The movement of the holder 14 may be stopped by hitting the cushioning material.

The deformation of the projecting piece 28 is not limited to the plastic deformation described above, but may be, for example, an elastic deformation.

Further, as in a modification shown in FIG. 6, a fragile breaking portion 28A may be formed near the base of the overhanging piece 28. In this case, when the lever holder 14 attempts to move downward by the axial impact force received by the shift lever 12, the overhanging piece 28 is pushed upward by the retainer 22 and is broken at the breaking portion 28A, and the shift lever 12 moves downward integrally with the lever holder 14 to absorb the impact force.
Even in this case, since the shift lever is offset from the fixed shaft 20 and the retainer 22, the shift lever 12
Can take a sufficient moving stroke.

FIGS. 7 to 10 show a shift lever device 50 according to a second embodiment of the present invention.

The shift lever device 50 has a shift lever 52 for a shift operation, and a knob 52A at the upper end.
The lower end of the shift lever 52 to which is attached is attached to a lever holder 54.

An insertion hole 56 is formed in the lever holder 54 downward from the upper surface, and the lower end of the shift lever 52 is inserted into the insertion hole 56 and fixed.

The lever holder 54 has a bracket 58 composed of a pair of parallel plates extending downward from the lower end. The lever holder 54 is mounted on the block 60 such that the bracket 58 holds the block 60 as an arm member from above.

On one end side of the block 60, a housing portion 62 opened downward is formed.
2, a substantially middle part of the fixed shaft 20 and the retainer 22 similar to those of the first embodiment is accommodated so as to be held. Further, the projecting piece 64 projecting from the opening edge of the housing portion 62 is swaged to clamp the fixed shaft 20 and the retainer 22 between the upper wall 62A of the housing portion 62. The retainer 22 only needs to be able to rotate integrally with the block 60. For example, the opening of the housing portion 62 may be completely closed by the overhanging piece 64. In this case, the block 60 is pressed into the retainer 22. Further, instead of the housing portion 62, a housing hole for housing the fixed shaft 20 and the retainer 22 may be formed at one end of the block 60, and the block 60 may be pressed into the retainer 22.

A lever holder 54 is provided at the other end of the block 60.
In the state where is mounted, the pin 66 is inserted into the insertion hole formed in the bracket 58 and the support hole formed in the block 60, and both ends of the pin 66 are crimped to prevent the pin 66 from falling off. At this time, a predetermined gap 68 is formed between the upper surface 60A of the block 60 and the ceiling surface 58A of the bracket 58. For this reason, the lever holder 54 rotates about the pin 66 as a rotation center within a predetermined range in which the ceiling surface 58A of the bracket 58 does not abut on the block 60.

In this state, the shift lever 52 is offset (length L) from the fixed shaft 20 and the retainer 22, and the axis 70 of the shift lever 52 does not intersect with the axis 24 of the fixed shaft 20.

A deformed piece 72 having a triangular shape in a side view is stretched and fixed between the side surface 54A of the lever holder 54 and the upper surface 60A of the block 60. Usually, the lever holder 54 is non-rotatably fixed to the block 60 by the deformed piece 72. The longitudinal direction of the lever holder 54 (vertical direction in FIG. 8) and the longitudinal direction of the block 60 (FIG.
(Right and left direction) form a right angle.

Therefore, also in this shift lever device 50, when the shift lever 52 is normally rotated by a shift operation, the lever holder 54 and the block 60 remain integrated, that is, the longitudinal direction of the lever holder 54 and the block 60 is rotated while forming a right angle with the longitudinal direction, and the retainer 22 is rotated to select an arbitrary shift range.

When the shift lever 52 is moved downward by receiving an impact force in the axial direction via the knob 52A, the other end of the block 60 is connected to the lever holder 54 via the pin 66.
, A rotational moment is generated in the direction of arrow C (see FIG. 8), and a prying force acts between the lever holder 54 that is to move downward and the block 60 that is to rotate. For this reason, as shown in FIG. 11, the deformed piece 72 (left side in FIG. 11) far from the retainer 22 is pulled and broken, and the deformed piece 72 on the side closer to the retainer 22 is broken.
(Right side in FIG. 11) is crushed. Thus, the lever holder 54 can be turned around the pin 66 with respect to the block 60. The block 60 is a lever holder 54
To rotate in the direction of arrow C, and the shift lever 52 and the lever holder 54 move downward while being integrated,
The impact force received by shift lever 52 is absorbed.

At this time, the shift lever 52 is
And the axis 70 of the shift lever 52 does not intersect with the axis 24 of the fixed shaft 20, so that when the shift lever 52 moves downward, the fixed shaft 20 and the retainer 22 Instead, the shift stroke of the shift lever 52 can be sufficiently taken.

The deformed piece 72 according to the second embodiment
Similarly to the deformation of the overhanging piece 28 according to the first embodiment, if the deformation can make the lever holder 54 rotatable with respect to the block 60 by the impact force received by the shift lever 52, Any deformation such as plastic deformation, elastic deformation, or fracture may be used.

The shift lever device of the present invention is not limited to the floor shift type provided on the center console of an automobile, but may be, for example, an instrument panel shift type provided on an instrument panel.

[0043]

As described above, the present invention can absorb the force without increasing the height by making the moving stroke of the shift lever sufficient when receiving a strong force.
